Re: %kds flexible number of keys

actually, i don't code it anyway, i use service pgm (one by file) and made a
little generator that code it for me.
wich include all operation : set (ll, ....), read (p, e...) write, delete,
update, clear, unlock, dft values ...)
with an external ds exporting the data.
